# sge(4)

Silicon Integrated Systems SiS190/191 Fast/Gigabit Ethernet driver

Part of [if\_sge(4)](/if_sge/4.md).

## NAME

**sge** – Silicon Integrated Systems SiS190/191 Fast/Gigabit Ethernet driver

## SYNOPSIS

To compile this driver into the kernel, place the following lines in your kernel configuration file:

**device miibus** **device sge**

Alternatively, to load the driver as a module at boot time, place the following line in [loader.conf(5)](/loader.conf/5.md):

```
if_sge_load="YES"
```

## DESCRIPTION

The **sge** device driver provides support for SiS190 Fast Ethernet controllers and SiS191 Fast/Gigabit Ethernet controllers.

All LOMs supported by the **sge** driver have TCP/UDP/IP checksum offload for transmit and receive, TCP segmentation offload (TSO), hardware VLAN tag stripping/insertion features. Due to lack of documentation Wake On Lan (WOL), Jumbo frame and an interrupt moderation mechanism are not supported yet.

The **sge** driver supports the following media types:

- **autoselect**

  Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to [rc.conf(5)](/rc.conf/5.md).

- **10baseT/UTP**

  Set 10Mbps operation.

- **100baseTX**

  Set 100Mbps (Fast Ethernet) operation.

- **1000baseTX**

  Set 1000baseTX operation over twisted pair.

The **sge** driver supports the following media options:

- **full-duplex**

  Force full duplex operation.

- **half-duplex**

  Force half duplex operation.

For more information on configuring this device, see [ifconfig(8)](/ifconfig/8.md).

## HARDWARE

The **sge** device driver provides support for the following Ethernet controllers:

- SiS190 Fast Ethernet controller

- SiS191 Fast/Gigabit Ethernet controller
